' 3 claims. (01. ear-"46) This invention relates to new and. useful improvements in concrete hauling and dispensing machines and the primary object of thepresent invention is to provide a device that will ride upon a roadway and lay concrete adjacent the roadway to increase the width of theroadway.

Another very important object of the present invention is to provide a wheeled trough having a dispensing end thatwill overhang a roadway over which the trough is propelled and a power operated worm within the trough for remixing concrete in which aggregate may have become segregated during transportation, and directing the remixed concrete toward the dispensing end of the trough.

Another object of the present invention is to provide an apparatus for widening roadways involving a dispensing trough having a deliver end that will overhang one side edge of a roadway and novel and improved means for guiding the trough and retaining one end of the trough over the side edge of the roadway as the trough is moved over the roadway.

A further object of the present invention is to provide a concrete hauling and dispensing machine that is so constructed as to have a large capacity for concrete but one that is actually compact in structure. p

'A still further aim of the Present invention is to provide a road widening apparatus including a trough having a dischargeend that will overhang the side edge of a roadway and an operators seat mounted on the overhanging discharge end to permit clear observation of the concrete as it is discharged from the trough. T 1

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had tothe accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, andinwhich:

Figure 1 is a side elevational view of the present invention, the numeral Iii represents a frame composed of a horizontal trough it having downwardly and inwardly inclined forward and rear walls It and I B that are joined at their lower ends by a smoothly curved bottom wall member i8, preferably integrally formed with the walls Hi and l 6.

The walls of the trough are reinforced and strengthened by any suitable number of struc tural members including groups of vertically inclined channels 2i; certain of which support depending arms 22. ihe lower ends of the arms 22 on the forward wall Id are horizontally apertured to receive a forward shaft 24 having wheels 25 thereon, and the lower ends of the arms on the rear wall it are also horizontally apertured to receive a rear shaft 23 having wheels 39 thereon.

The shafts 2 5 and 28 extend longitudinall of the trough i2 and the wheels 26 and 3d are disposed transversely of the trough whereby the trough may be moved laterally over a roadway R.

One end 32 of the trough i2 overhangs one side edge E of the roadway R, see Figure 3, and is provided with a delivery opening 36 in which V87.- tical guide plates 36 are mounted. The opening 34 extends through the walls :4, Hi and it but mostly through the wall it asshown in Figure 5.

An elongated screed and finishing member is adjustably secured to the rearmost of the guide machine supported upon a roadway and attached to a prime mover; I v s Figure 2 is a side View of the machine taken from the opposite side of Figure 1;

Figure 3 is a rear elevational view of Figure 2;

Figure 4 is an enlarged fragmentary top plan view of Figure 3; and,

Figure 5 is a detail vertical sectional view taken substantially on the plane of section line 5-5 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present plates 3511 by fasteners it that enter vertical slots 39 in the member 38 for vertical adjustment of the member 38, and the member 38 includes a fiat horizontal portion d2 whose lower face will be flush with the uppersurface of the roadway. The member 38 and its portion &2 extend the length of the overhang end portion 32 as shown in Figure 3.

The end portion 32 is provided with a vertical end. wall 4d that supports an elongated strip it that is connected to an elongated pliable or rubber member or skirt board 38. The member i3 is reinforced and connected to the strip 46 b a flexible or pliable strip 56, and the strip 56 is vertically slotted, as at 52, to receive fasteners 54 carried by the wall 4 for vertical adiustment'of the skirt board. The skirt board idis suiiiciently stiif to strike off the fresh concrete to the elevation of the top of the forms but pliable enough to ride over irregularities of the road form without tearing up the forms or injuring the machine as a steel guide plate would do.

A concrete form F parallels the edge E and underlies the skirt board 48 thereon as shown best in Figure 3 of the drawings. An operators seat 56 is supported on the end portion 32 to per- 3 mit an operator to observe concrete discharged through the opening 34 and is so located as to permit an operator to observe concrete as it is remixed and forced through the trough toward the opening at, the latter operation being performed by a conveyor screw 58 that is disposed horizontally within the trough l2 and which includes end portions that are rotatably supported in bearings carried by the end walls of the trough.

The frame it supports a power plant 60 "whose drive shaft 92 is connected to the end of the screw 58, remote from the seat 59, by a drive connection i l. The clutch of the power plant is actuated by a horizontally slidable rod 66 that is slidably supported by bearings 58 and 19. The former bearing es, being supported by a cross-rail 12 mounted within the trough.

The forward wall is and more specifically two of the member 22 carried by the forward wall M, support a pair of tongue members or pull bars Hi that are attached to a prime mover or vehicle "#3 whereby the machine may be pulled over the roadway.

Means is provided for guiding the machine as it is pulled over the roadway and for retaining the end portion 32 overhung with respect to the edge E. This comprises a vertical rod 13 depending from the wall it at the end portion 32 and which supports a horizontal roller 89 at its lower end that rides against the edge E.

A splash shield 82 depends vertically from the trough and is located close to and parallels the edge E to restrict the splashing of concrete upon the surface of the roadway.

An elongated angle iron as, is mounted in the trough and is welded to one wall of the trough. The angle iron 83 extends the full length of the trough to form a small shoulder for the auger blades to turn against. The angle iron 33 prevents larger rocks in the concrete from get ting underneath the worm and causing the worm to stop rotating, Or to be bent if forced to rotate.

In practical use or the present invention, the trough i2 is filled with concrete and the machine is pulled over the roadway R. As the rod 66 is pulled, the screw 53 is rotated to remix the concrete and conduct the concrete toward the opening Eli whereupon the concrete will pass through the opening and lie between the form F and edge E.

The member 38 will smooth the concrete level with the surface of the roadway and will push excess concrete forwardly.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingl deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the claimed as new is:

1. A concrete hauling and dispensing machine comprising an elongated horizontally disposed remixing trough, wheels supporting said trough and adapted to permit lateral movement of the trough over a paved roadway, said trough including an end portion adapted to overhang one side edge of a roadway, the said end portion of said trough having a dispensing opening therein, a pliable smoothing member adjustably secured to the said end portion of said trough and including a horizontal portion adapted to overlie a form paralleling the side edge of a roadway overhung by the said end portion, and means carried by said trough for engaging the side edge of a roadway to align the trough as the latter is moved over the roadway.

2. A concrete hauling and dispensin machine comprising an elongated horizontally disposed remixing trough, wheels supporting said trough and adapted to permit lateralrnovement of the trough over a paved roadway, said trough ineluding an end portion adapted to overhang one side edge or a roadway, the said end portion of said trough having a dispensing opening therein, a member adjustably secured to the said end portion of said trough and including a pliable horizontal skirt board adapted to overlie a form paralleling the side edge of a roadway overhun by the said end portion, guide means for the trough and mounted at the said end portion of the trough, and a horizontally disposed worm mounted in the trough for remixing concrete and for directing remixed concrete in the trough toward said opening.

3. The combination of claim 2 and an elongated angle iron flxed in said trough and extending through the length of the trough, said angle iron constituting a shoulder against which said worm rides to prevent large rocks from getting underneath the worm.
